Is the Technics SL7 basically the same mechanically as the SL5 and SL6? I know it has a different lid and heavier build but are the tangential arm mechanisms silmilar for example. I have a working SL5 and a non working spares SL5. I like these turntables very much and chose the SL5 over the SL6 as it does not have the added complication of track programming. However, I would like to get hold of an SL7 and wondered if my SL5's can act as donors in the event I have problems with this in the future. Thanks.
Manuals for both the SL-5 and the SL-7 are available from Vinyl Engine.

I'm not sure why I didn't think of looking at the SL7 manual. I have the manuals for the SL5 from VE. Seems obvous now. Thanks.
It looks like the arm and servo system are pretty similar but there are differences in the electronics. Some circuitry that is on separate PCB's on the SL5 has been incorporated into a larger main board on the SL7. The SL7 also uses slightly different IC's to the SL5 although I think operationally they do the same thing. Need to think about whether I really need to buy an SL7 as the SL5 sounds pretty good and I have a supply of ready spares.
Hi. Great works of art and engineering these linear turntables.
I have acquired a Technics SL-10 (1982 !!).
I don't have the EPS 310MC cartridge that was with it.
I am using the Technics P 30 S cartridge with JICO elliptic stylus.
I simply did a little maintenance by replacing the tonearm motor belt, lubricating the same mechanism with silicone with teflon and placing 500,000 silicone in the descent of the tonearm.
Great turntable; silent perfect rotation stability; Very well muffled and great sound.
It is a pity that the EPC 310 MC does not already have a MM-MC selectable mobile coil cartridge preamplifier incorporated.
Greetings.

Hi ALPUY!
At the polar opposite end of the quality scale from your SL-10, I have a Technics SL-3 in my collection. The SL-3 is a DC servo control belt drive linear tracker. I bought it new, as part of a midi system, for my then wife-to-be and it sure looks the business with its chunky aluminium platter. The tone arm descends rather abruptly though and I could do with your assistance in replacing the damping fluid! But no matter as I retain it mainly for its looks and tend to spin my vinyl elsewhere. 🙂

I would love someone to correct me but on my SL5, there appears to be no way of refilling the lowering device with damping fluid. I had mine stripped down and could see no way of doing this. The arm on my turntable drops quite quickly as well and although I don't think it is causing any damage to the cartridge, I would like it to be slower. I am pretty sure the SL7 and perhaps the SL6 have the facility to top up fluid but not in models before that. Like I say, I would love to be corrected.
Scroll down to the diagrams taken from the SL-5 manual in this link:

Not for the fainthearted! Perhaps ALPUY will share his experience.
Thanks Galu. This post seems to have appeared after I had had my SL5 in bits for a good clean (having bought it on eBay). I shall investigate this post with interest. Thanks again.
An externally hosted image should be here but it was not working when we last tested it.

The Technics turntable tonearm buffer I think is all similar.
There is a cylinder with a central shaft lubricated with dense silicone (300,000 to 500,000). Operated with a solenoid which, when activated, drops the tonearm.
It is easy to remove. Just screw and remove it to the right.
I advise photographs at each step of disarmament and then assemble it correctly.
The silicone is placed between the cylinder and the shaft.
Place the "lever" as it is in the photo before disassembly.
Greetings.
